The word(s) "arm" appears 65 time(s) in 60 verse(s) in Quran in Muhammad Pickthal translation.

(31) Say: As for him who is in error, the Beneficent will verily prolong his span of life until, when they behold that which they were promised, whether it be punishment (in the world), or the Hour (of doom), they will know who is worse in position and who is weaker as an army.

(32) And thrust thy hand within thine armpit, it will come forth white without hurt. (That will be) another token.

(33) He said: Worship ye then instead of Allah that which cannot profit you at all, nor harm you?

(34) And We taught him the art of making garments (of mail) to protect you in your daring. Are ye then thankful?

(35) He calleth unto him whose harm is nearer than his benefit; verily an evil patron and verily an evil friend!

(36) These twain (the believers and the disbelievers) are two opponents who contend concerning their Lord. But as for those who disbelieve, garments of fire will be cut out for them; boiling fluid will be poured down on their heads,

(37) Lo! Allah will cause those who believe and do good works to enter Gardens underneath which rivers flow, wherein they will be allowed armlets of gold, and pearls, and their raiment therein will be silk.

(38) Though We had mercy on them and relieved them of the harm afflicting them, they still would wander blindly on in their contumacy.

(39) Or do they benefit or harm you?

(40) (Remember) when Moses said unto his household: Lo! I spy afar off a fire; I will bring you tidings thence, or bring to you a borrowed flame that ye may warm yourselves.
